  • Patent number: 11279796
    Abstract: A heat-curing epoxy resin compositions which can in particular be used as bodyshell adhesives for motor vehicle construction. The heat-curing epoxy resin compositions contain a curing agent which can be activated through elevated temperature and has a first component K1 containing at least one epoxy resin and a second component K2 containing at least one tertiary amine and also a primary amine. These compositions, after short-term heating of 30 to 120 seconds at a temperature of 90° C. to 130° C., exhibit sufficient strength and adhesion to withstand transport-induced mechanical strains.

  • Patent number: 10738226
    Abstract: A one-component heat-curing epoxy resin adhesive has at least one epoxy resin having an average of more than one epoxy group per molecule; at least one latent hardener for epoxy resins; and at least one carboxylic acid selected from substituted or unsubstituted adipic acid, substituted or unsubstituted succinic acid, substituted or unsubstituted phthalic acid, substituted or unsubstituted terephthalic acid, substituted or unsubstituted isophthalic acid, substituted or unsubstituted benzenetricarboxylic acid and substituted or unsubstituted nitrobenzoic acid, excluding 2-hydroxysuccinic acid and 2,3-dihydroxysuccinic acid as carboxylic acid, and wherein the epoxy resin adhesive contains 0.0015 to 0.04 mol of the at least one carboxylic acid per 100 g of the epoxy resin adhesive and the epoxy resin adhesive has a viscosity of 500-5000 Pas at 25° C. The epoxy resin adhesive is notable for a very heat-resistant bond on particular metal substrates such as steel having a zinc-magnesium coating.

  • Patent number: 9512341
    Abstract: The present invention relates to heat-curing sealant compositions including at least epoxy resin, dicyanodiamide or an amine complex of a Lewis acid, polyurethane polymer (PUP) containing isocyanate groups and polyaldimine. These single component sealant compositions are characterized by a rapid skin formation and high tensile strength. Because of the short skin formation time, said compositions are optimally suitable for use as sealants in autobody work because they can be excellently layered on top of same.

  • Patent number: 9139682
    Abstract: A foam is disclosed that can be cured by heat having, for example, 10 to 80 vol. % of at least one gas and a compound that can be cured by heat. The foam can include at least one polyurethane polymer and at least one curing agent that can be activated by increased temperature. Foams that can be cured are suitable as flues, sealing compounds, or for the production of coatings, and can be cured by heat for structural adhesive bonds and for lining in vehicle construction.

  • Patent number: 9034135
    Abstract: The present invention relates to a method of producing an edging-fold bond. For this purpose use is made more particularly of high-viscosity adhesives. The method features reduced bubble formation within the edging fold and also within the sealant (where present) that seals the edging-fold seam. More particularly the adhesive comprises spacers which further reinforce this effect.

  • Publication number: 20130280526
    Abstract: The invention relates to heat-curing sealing compound compositions comprising at least epoxy resin, a heat-activatable hardening agent or accelerators (B) for epoxy resins, isocyanate group-containing polyurethane polymer (PUP) and a special polyaldimine. Said single-component sealing compound compositions are characterized by a good skin formation time and extraordinarily good storage stability and low blistering. Due to these properties, said sealing compound compositions are optimally suitable for use as sealants in autobody work because they can be excellently coated with a KTL paint.

  • Publication number: 20010053827
    Abstract: Described are adhesives that in usual climatic conditions are storage stable over a certain period of time and that cure upon the application of an activation step. The inventive adhesives at room temperature have a thermoplasticity similar to butyl rubber and thus are plastically deformable upon joining of construction elements with the pressure necessary for such joining, and do not have a tendency for crack formation. In a lot of cases, said inventive consistency enables direct adhesion without the necessity of mechanical fixation.
